Adding a new tab in tabview with webview?

I added the code for the add tab but I'm getting errors I tried for a couple of days to correct the errors. I need some assistance. I posted the code below with a screenshot` of code here` of the new tab button.

         private void AddTab_Click(object sender, RoutedEventArgs e)
         {
             var newTab = new TabViewItem();
             newTab.IconSource = new SymbolIconSource() { Symbol = Symbol.Document };
             newTab.Header = "New Tab";
    
             Frame frame = new Frame();![8012-error.png][1]
             newTab.Content = frame;
             frame.Navigate(typeof("www.msn.com"));
    
             sender.TabItems.add(newTab);
         }

In addition to the 2 errors in the image attached I think that there is this error too: you are trying to open a website with a Frame, I think you need a WebView.

Moreover I think that you are using Microsoft.Toolkit.Uwp.UI.Controls.TabView but you are looking sample code for Microsoft.UI.Xaml.Controls.TabView

Microsoft.Toolkit.Uwp.UI.Controls.TabView comes with Microsoft.Toolkit.Uwp.UI.Controls NuGet package
Microsoft.UI.Xaml.Controls.TabView comes with Microsoft.UI.Xaml NuGet package

Try to change your method in this way:

private void AddTab_Click(object sender, Windows.UI.Xaml.RoutedEventArgs e)
{
    var newTab = new TabViewItem {Icon = new SymbolIcon {Symbol = Symbol.Document}, Header = "New Tab"};

    WebView frame = new WebView(); 
    newTab.Content = frame;
    frame.Navigate(new Uri("http://www.msn.com"));

    Tabs.Items.Add(newTab);
    Tabs.SelectedItem = newTab;
}

I tried the suggestion the system has been giving me, but it fixes one thing and breaks the others

Which is the x:Name of your TabView in the XAML? Replace "Tabs" with the x:Name of the TabView.

@danielescipioni I changed the name, it corrected the problem. but now it's moving really slow, and when I have more than one tab the first tab displays the website I want the second tabs title changes but the site stays the same

I think this thread is going out of the scope of the original question.

Would be nice if you can mark my answer as accepted (if you this that the answer is OK) and post another question for the icon and title.

Hi Mark,

Have you added Microsoft.Toolkit.Uwp.UI.Controls.dll assembly?
